Canadian chemists say they have discovered green catalysts made from iron that might replace more expensive and toxic platinum metals.
University of Toronto scientists said the newly discovered catalysts might become useful in industrial chemical processes used to produce drugs, fragrances and flavors.
The researchers led by Professor Robert Morris said drug synthesis most often relies on the use of catalysts, while the cost of those catalysts influences the ultimate cost of the drug.

A University of Toronto research team from the Department of Chemistry has discovered useful "green" catalysts made from iron that might replace the much more expensive and toxic platinum metals typically used in industrial chemical processes to produce drugs, fragrances and flavors.

Kalin Lucas touched off a 21-point run that spanned halftime Friday and sent Michigan State roaring past Robert Morris 77-62 in the NCAA Tournament.
